Very Front-Focused Nikon D7100

Hi all, I just bought a new D7100 a few weeks ago and on it's first run-out I noticed that it was front-focused so today I spent 30mins shooting a bricked path and using that to visually adjust it as best I could.

I found that all three of my lenses (35mm/50mm Nikon and 70-200mm Tamron) needed between +12 to +16 (out of 20) to get about 95% of the focus (by my eye anyway) using the LCD and zooming in. Obviously it's not going to be 100% without a proper test set-up but it'll do for now however are those figures something that you would consider "bad" enough to return the camera under warranty repair for?

Cheers.......................................Ian

yes, it is consistently miles out so I would look for a warranty repair.

I would liekly return it or better still, send it in to Nikon with all your lenses to get a complete system calibration.

There isn't really a problem with having to micro adjust all your lenses. However, at some point in the future if you get a badly back focusing lens then you might not have sufficient control to correct it if your camera font focuses.

I have same issue with my D3300 kit. Is this something they would fix this as it is a low end body/lens?

To get something in focus I need to move the camera a whole foot closer after locking focus. It's pretty annoying and ridiculous.

On the other hand, live view autofocus is unbelievably accurate, which is a shame as I use the viewfinder 99% of the time.

Of course, jesus, your camera sounds horrific.

Focus accuracy should be within a few millimeters when calibrate and focus conducted properly.

Thanks for the replies, I remembered I bought Focal a few years ago for my 7D so I've re-installed the new V2 which came out yesterday and I'll give it a bash over the weekend but I'll probably still send it back in the next few weeks for the reasons D.P mentioned.
